Question

我正在尝试测试一个组织为Python包的Django可重用应用程序。这是目录树：

reusableapp
├── __init__.py
└── submodule
    ├── __init__.py
    └── app
        ├── __init__.py
        ├── models.py
        ├── tests.py
        └── views.py

我的Django版本是1.5。要选择要测试的应用程序，我有以下代码，基于暴露的here：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

"""
Description: Execute tests from outside Django's project
"""


import os
import sys

from django.conf import settings


DIRNAME = os.path.dirname(__file__)

INSTALLED_APPS = [
    "reusableapp.submodule.app"
]

settings.configure(
    DEBUG=True,
    DATABASES={
        "default": {
            "ENGINE": "django.db.backends.sqlite3",
        }
    },
    INSTALLED_APPS=tuple(INSTALLED_APPS),
    CACHES={
        "default": {
            "BACKEND": "django.core.cache.backends.locmem.LocMemCache",
        }
    },
)


if __name__ == "__main__":

    from django.test.simple import DjangoTestSuiteRunner

    test_runner = DjangoTestSuiteRunner(verbosity=1)
    failures = test_runner.run_tests(INSTALLED_APPS)
    if failures:
        sys.exit(failures)

但是当我执行它时，我得到了以下错误（使用virtualenv）：

(reusableapp) $ python runtests.py
Traceback (most recent call last):
  File "runtests.py", line 48, in <module>
    failures = test_runner.run_tests(INSTALLED_APPS)
  File "/var/lib/virtualenvs/reusableapp/local/lib/python2.7/site-packages/django/test/simple.py", line 369, in run_tests
    suite = self.build_suite(test_labels, extra_tests)
  File "/var/lib/virtualenvs/reusableapp/local/lib/python2.7/site-packages/django/test/simple.py", line 254, in build_suite
    suite.addTest(build_test(label))
  File "/var/lib/virtualenvs/reusableapp/local/lib/python2.7/site-packages/django/test/simple.py", line 102, in build_test
    app_module = get_app(parts[0])
  File "/var/lib/virtualenvs/reusableapp/local/lib/python2.7/site-packages/django/db/models/loading.py", line 160, in get_app
    raise ImproperlyConfigured("App with label %s could not be found" % app_label)
django.core.exceptions.ImproperlyConfigured: App with label reusableapp could not be found

我在Django文档中搜索了可重用的应用程序和格式，但除了"just a Python package that is specifically intended for use in a Django project. An app may also use common Django conventions, such as having a models.py file"之外没有其他内容

你知道一些明确的约定/ requeriment，它可以解释可重用的应用程序格式吗？如果没有，你有没有遇到过这种情况？有没有办法强行加载应用程序？

谢谢你，并致以最诚挚的问候。

让我们说您的应用路径是/ parentdir / reusableapp / submodule / app

首先通过在python解释器中运行以下命令，确保你的PYTHONPATH中有/ parentdir /： -

>>> import os
>>> os.environ['PYTHONPATH'].split(os.pathsep)

您可能不会看到此路径，请在django项目manage.py文件中添加以下行。

sys.path.append('/parentdir/')

另外 -
您是否检查过在TEMPLATE_LOADERS中设置django.template.loaders.app_directories.Loader，如果还没有，请尝试像这样添加它 -

TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
)

关于模板子目录的django文档 - https://docs.djangoproject.com/en/dev/ref/templates/api/#using-subdirectories

希望它会有所帮助。
